    {
        try
        {
            Usercls u = new Usercls();
            if (e.CommandName == "upd")
            {
                int uid = Convert.ToInt32(e.CommandArgument);
                Session["uid"] = u.GetUserbyID(uid)[0].UserId.ToString();
                Session["fname"] = u.GetUserbyID(uid)[0].FirstName;
                Session["lname"] = u.GetUserbyID(uid)[0].LastName;
                Session["uname"] = u.GetUserbyID(uid)[0].Username;
                Session["des"] = u.GetUserbyID(uid)[0].Designation;
                ImageButton upd = (ImageButton)e.Item.FindControl("updbtn");
                upd.OnClientClick = "return PopUp()";
            }
            else if (e.CommandName == "del")
            {
                int uid = Convert.ToInt32(e.CommandArgument);
                u.DeleteUser(uid);
                rptuser.DataBind();
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

Repeater ===>

<pre lang="xml"><asp:Repeater ID="rptuser" runat="server" DataSourceID="ObjectDataSource1"
               OnItemCommand="rptuser_ItemCommand">

        <td class="GridItems"><%# DataBinder.Eval(Container.DataItem,"Username") %></td>
        <td class="GridItems"><asp:ImageButton ID="updbtn"   ValidationGroup="Av" runat="server" ImageUrl="~/images/update.jpg"   CommandName="upd" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"UserId") %>' /></td>
       </tr>
       </ItemTemplate>
       <FooterTemplate>
       </table>
       </FooterTemplate>
       </asp:Repeater>

Solution 1

When you first click it binds the client script to popup. And that is why you have to click it again to get the popup.

Change upd.OnClientClick = "return PopUp()"; to ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", "window.open('urlhere');", true);

function PopUp()
{
var winTop = (screen.height / 2) - 125;
var winLeft = (screen.width / 2) - 125;
var windowFeatures = "width=300,height=250,";
windowFeatures = windowFeatures + "left=" + winLeft + ",";
windowFeatures = windowFeatures + "top=" + winTop;

window.open("EditUser.aspx","EditUser",windowFeatures);
}

on the first click your upd.OnClientClick = "return PopUp()"; is getting registered and then on second click it actually gets popup. so you need to register the click event on page load.

updbtn.Attributes.Add("onClick", "window.open('EditUser.aspx','','width=700,height=700');return false;");

this works.. i have checked...U need to add this event

protected void rptuser_ItemCreated(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
ImageButton _myButton = (ImageButton)e.Item.FindControl("updbtn");
_myButton.Attributes.Add("onClick", "window.open('About.aspx','','width=700,height=700');return false;");
}
}

2) If you are populating the repeater like in Bind() method call the method after updating.

private void Bind()
    {
        //connection command datatable...      
        Repeater1.DataSource = dt;
        Repeater1.DataBind();
    }
